SHINGLE-MACI-IINE.

Specification of Letters Patent No. 8,691, dated January 27, 1852. i

The nature of my invention consists inan improvement in VVoods patent self feeding shingle machine for cutting and Jointing shingles.

This improvement consists in this: I do not use the machinery for self feedingbut inmy improvement you feed by hand.

I use a vibrating rod D see drawings) `attached by a pitman rod E to the knife sash B which plays up and down in grooves inthe posts C, C, which are rmly fastened at an angle of forty-ve degrees to the shingle bench A. This vibrating rod moves up and down with the knife sash in a groove in the post Gr, and gages the thickness of the shingle and causing one end of the shingle to be thicker than the other.

What I claim as my invention and desire to secure by Letters-Patent is- The application of the vibrating rod gaging the shingles. The shingle blocks are laid on the bench A and are pressed against the vibrating nod D one end resting against the center panel of the knife sash B, Vthen as the sash moves up and down the shingles are cut off the block and finished at one` stroke of the machine, while the block can be turned at leisure to snit the grain of the wood.
